TO ALL WHOM IT MAY CONCERN:

Be it known that I, PLATT C. INGERSOLL, of Greenpoint, in the county ofKings, and State of New York, have invented certain new and usefulImprovements in Spring-Bed Slate; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, making a portion of thisspecification, in whichl Figure l is a plan view' of a spring-bed slatmade according to my invention.

Figure 2 is a side view of the same.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention may be considered as an improvement' on the bed-Slatpatented by PLATT C. INGERsoLL,

October 31, 1865, and its'object is to render the said Slat moreyielding and elastic, without in any way impairx ing its strength ordurability; and to this end it consists in certain novel combinations ofsupporting-springs with the sheet-metal and slut-bars, whereby thedesired object is perfectly secured.

'.lo enable others'to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.

A represents a wooden strip, which constitutes the bottom of the slat,and which may be of any suitable width, and of a length proportioned tothat of thc bedstead upon which theslats are to be employed. Situatedtransversely at one end of the strip, and -projecting upward therefrom,is a block or piece, a, and situated near the opposite side is a lowtransverse cleat, b. B represents the sheet-metal slat-bars, which maybe made of hoop-iron, and of which there are one or more, but preferablytwo to each strip, A. These Slat-bars, B, are fastened at one endto-fone extremity of the strip A, and, passing over the block ohr piecea, have secured to their under sides, near their opposite ends, a shorttransverse bar, c, the ends last mentioned being secured in anyappropriate manner to the adjacent end of the strip A. A stiff spring,f,is placed between the cleat b and the bar c, and at intervals,underneath the horizontal portions of the Slat-bars, between the sameand the strip y A, are spiral or other suitable springs, g, the upperends of which support cross-bars h, secured to the Slat-bars,

so that the aforesaid springsg serve in a measure to sustain thehorizontal portions of the said Slat-bars against the pressure ex-ertedby any weight placed thereon.

When the slats are in use, the weight upon the slot-bars, by somewhatdepressing the central parts of the horizontal portions thereof, tendsto elongate, as it were, the said horizontal portions. The spring f, byyielding slightly, allows of such elongation, without permitting anyundue depression of the ends of the Slat-bars adjacent thereto; whilethe springs g, by sustaining the aforesaid horizontal portions of theSlat-bars, enable themy to support the weight upon them, and at. thesame time render the same more elastic, and consequently morecomfortable to the person supported-thereby.

What I claim as my invention, and desire to secure by Letters Patent, is

The springs j' and g,'in combination with the sheet-metal Slat-bars B,and arranged in relation to the end and horizontal portions of saidSlat-bars, substantially as and for the purposes speciiied.

P. C. INGERSOLL.
